The upper portion, that has been crafted from premium full-grain waterproof leather, features cooling side venting, and has been coated with HydroGuard's waterproof membrane for further protection. The in-shoe portion has a removable Polysport anti-microbial footbed which allows for increased underfoot airflow, and maintains cooler temperatures while offering improved cushioning. The PowerUp outsole system houses a compression molded EVA midsole that keeps the shoe lightweight, and adds further cushioning.
